CHANNELlNG-MACHINE FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 262,689, dated August15, 1882.

Application filed June 23, 1882.

T all whom it may concern:

Be it known that I, THOMAS NOLAN, ofBrockton, in the county ofPlymouth,State of Massachusetts, have invented a certain new and usefulImprovement in Channeling-Machines for Boots and Shoes, of which thefollowing is a description sufficiently full, clear, and exact to enableany person skilled in the art or science to which said inventionappertains to make and use the same, reference being had to theaccompanying drawings, forming a part of this specification, in whichFigure l is a perspective view, showing the under side of the arm of thechanneler and the mechanism attached to the same, the auxiliary cutterbeing elevated; Fig. 2, a perspective view of the auxiliary groovecutter or gouge detached; Fig. 3, an isometrical perspective view,showing the head of the machine reversed or from the under side, withthe auxiliary cutter depressed; Fig. 4, a sectional view of a shoe-solechanneled by my improved machine, and Fig. a vertical transverse sectiontaken on the line a; m, Fig. 4.

Like letters of reference indicate corresponding parts in the differentfigures of the draw- 1ngs.

My invention is designed as an improvement on the boot and shoechanneling machine now in extensive use and known as the McKay, Goodyearand McKay, or Vrooman channeler; and it consists in the employment of anauxiliary groove cutter or gouge for cutting a stitch-groove in thebottom of the channel in the sole, in combination with mechanism foroperating the same to bring it into and throw it out of contact with thesole whenever de- (No model.)

will be but one stitch-groove in the channel at that point. Myinvention, which will be readily understood by the followingdescription, enables this to be done with greater facility and moreperfectly than it has het etofore been accomplished.

In the drawings, A represents the arm ofthe machine; B, the shaft; 0,the guide or presscr wheel; D, the knife for cutting the channel a andproducing the flap d, and E the cutter or gouge for forming thestitch-groove m. These parts, being all common and well known, need notbe more particularly described.

G is the auxiliary cutter or gouge employed for cutting or forming thestitch-groove z in the sole-channel a. This cutter is attached to theunder side of the arm A by the screws a, and provided with theeccentric-shaft J, having the handle or lever H, by which it may beraised or lowered as the eccentric is turned in its hearings in the armbeneath the cutter. The free end or gouge proper of the cutter G isformed as seen at h in Fig. 2, and the body, or that portion lying onthe arm A, being of steel, yields or springs sufficiently when actedupon by the eccentric (not shown) on the shaft J to permit the part itto rise above or fall below the knife D, as required.

In Fig. 1 the gouge h is represented as elevated or in position forcutting the groove 2, the lever. H being in juxtaposition with the wheel0. j

In Fig. 5 the gouge h is represented as depressed or out of contact withthe sole, the lever H being swung into a position opposite that shown inFig. 1, or as far as possible from the wheel 0. I

It should be remembered that Figs. 1 and 3 represent the arm A and itsattached parts reversed or upside down, and that when it is stated thatthe gouge his elevated in Fig. 1 and depressed in Fig. 3, the statementhas reference to the position of the gouge in these figures only, as thegouge has in reality to be depressed to be brought into contact with thesole, and elevated to be thrown out of contact therewith.

In the use of my improvement the gouge h is arranged in the positionindicated in Fig. 1 by moving the lever H toward the wheel 0, and thetwo grooves m 2 out around the fore part of the sole. When the cuttersarrive at the shank or that portion of the sole where but one groove isrequired the lever H is moved away from the wheel G and the gouge hthrown out of contact with the sole in a manner which will be readilyunderstood by all conversant with such matters without a more elaboratedescription.

It will be obvious that the cutter G may be operated or raised andlowered by other means than the crank J and lever E, if desired; also,that the gouge h may be connected to a slide or arm and'operated by atreadle and various mechanical devices without departing from the spiritof my invention.

It will also be obvious that in some classes of work where but onestitch-groove is required in the bottom of the channel the fixed cutteror gouge E may be dispensed with; also, that two or more cutters orgouges so constructed and arranged as to be moved into and out ofcontact with the sole may be employed, if desired, either with orwithout the fixed gouge E.

I am aware that in many wood, iron, and leather working machines inwhich more than one cutter are employed it is common to so arrange oneof them that it may be thrown out of use during the process of cuttingwhenever desired without interfering with the operations of those leftin use, and therefore do not claim such an arrangement, broadly; but,

Having thus described my improvement, what I claim is- 1. In a machinefor channeling the soles of boots and shoes, the cutter G,eccentric-shaft J, and lever H, in combination withthe knife D and armA, substantially as specified.

2. In a machine for channeling the soles of boots and shoes, a cutter orgouge for forming a stitch-groove in the bottom of the channel, adaptedto be moved into and out of contact with the sole and its operatingmeans, in combination with a knife for cutting the channel and formingthe channel-flap, substantially as set forth.

THOMAS NOLAN.
